LUBRICANT-CUP.

A To .all whom t may concern Be it known that I, GEORGE L.` LANG, a citizen of the United States, residing at Newark in the county of Essex and State of New Jersey,l have invented certain new `and useful Improvements in Lubricant- Cups, of which the following is ay specification. s

My invention relates to means for furnishing lubrication to shaft bearings and `other such machine parts wherein continual contact motion` with .associated elements s necessitates a 'sufficient amount of lubrication to avoid undue friction `and wear. Inparticular lit pertains tol means for applying lubricants of that"` class havinga thick and dense consistency such as lubricating grease and the like; i In many machine constructions andespecially those of acomplicated nature, it is almostinvariablythe case thatcertain movfable .elementsareadapted to be operated at .higher speeds or under greater load condilvtionsv than is the case with other parts of the l 2s5"Ir'iechanism,.A Consequently it is necessary that a greater amount of lubrication be supplied,.and.at'inore frequent intervals, to the bearings and journals of oneelement Athan ,towtho'se of anothelp In view of such rethatfany suitable amount of' lubrica- .f'iiigwhile at the same time it' includes means 1'to`assure the operator that the proper amount .hasbeen applied ineach case.4

" Fig. 2 is a planview of the cup completely assembled, looking as from the bottom of Fig. l, and, s

Fig. 3 illustrates a bottomplan view of the cap portion of the device, showing the mlanner of attaching the resilient member in p ace. 'Referring to the drawing` wherein like reference characters identify corresponding parts throughout the several views, 1 is the .cap member which is formed in the shape of a cylindrical cup, and may if desirable, y from flat stock of any suitable material. In its formation the head or closed end 2 of saidcap is preferablyL left 'somewhat thicker than the wall yportions and is provided with a peripheral shoulder 3. which may be milled or knurled in any ,sultablefashiom as seen in Fig. 3, to permit `a finger hold for .turning said cap. On its `lnterlor surface, member` 1 has a screw thread 4 which extends substantially throughout the entire depth of the cup. Secured Within the cap'l, 'as by means of a rivet 5 passing through the head 2, is a resilient member 6, such as a leafsprmg, havingv at its fixed end a semicircular portion 7. This l. semicircular portion has a diameter corresponding to that of cap 1 so that-whenv fixed in place by rivet 5 or ysome equivalentA 'means, said leaf spring 'is always 'held "againstlthe liability, of' displacement.

A lubricant device having in combination, a hollow body memberconstructed of flat material, a cap member screw threaded thereupon for axial movement relative thereto, a leaf spring having an enlarged semicircular portion at one end by means of which the same is securely fastened to the bottom of said cap, and an orifice in the end of the body member, said body member having a substantial portion of its length internal and external fiat surfaces, said eX- ternal surfaces serving as a means to apply the body member in its working position, said leaf spring having its free end disposed so as to engage at the intersections of said internal flat surfaces for the purpose of holding said ca securely in its adjusted position upon the body member.

4. A lubricant device having in combination, a hollow body member punched from fiat stock, a cap member screw threaded thereupon for axial movement relative theret0, a resilient member secured at one end of said cap, and an orifice in the end of said body member, said body member havin a substantial portion of its length provied with a series of internal angular surfaces, said resilient member having its free end in Copies of this patent may be obtained for prpssing engagement with said angular surfaces in order to hold the cap in adjusted position upon said body member, said angular surfaces tapering in such a way that the pressure exerted thereupon by the resilient member is a minimum when the ca is at its extreme uppermost position on sai body, thereby facilitating the threading of said cap upon the body member after said device has been inspected or replenished with lubricant.

5. A lubricant device having in combination, a hollow body member constructed of fiat material, a ca member screw threaded thereupon for axia movement relative thereto, a leaf spring having an enlarged semicircular portion at one end, a fastening member passmg through the head of the ca and said semieircular portion to secure sai leaf spring in place within saidV cap member, and an orifice 1n said hollow body, said body having a portion of its length provided with angular surfaces with which the free end of said spring flexibly coperates for the purpose of retaining the cap member in its adjusted position upon the body member, said cap bein adapted to force lubricant through sa1d ori ce when turned upon the body member, and said fastening member serving also as a visible indicator to enable the operator to ive said cap the desired number of turns.
